mc54/74hc4060 highspeed cmos logic data dl129 e rev 6 7 motorola design procedures the following procedure applies for oscillators operating below 2 mhz where z is a resistor r1. above 2 mhz, additional im - pedance elements should be considered: c out and c a of the amp, feedback resistor r f , and amplifier phase shift error from 180 . step 1: calculate the equivalent series circuit of the crystal at the frequency of oscillation. jx c o (r s + jx l s jx c s jx c o + r s + jx l s jx c s z e = = r e + jx e reactance jx e should be positive, indicating that the crystal is operating as an inductive reactance at the oscillation frequency the maximum r s for the crystal should be used in the equation. step 2: determine b , the attenuation, of the feedback network. for a closedloop gain of 2, a n b = 2, b = 2/a n where a n is the gain of the hc4060 amplifier. step 3: determine the manufacturer ' s loading capacitance. for example: a manufacturer may specify an external load capaci - tance of 32 pf at the required frequency. step 4: determine the required q of the system, and calculate r load . for example, a manufacturer specifies a crystal q of 100,000. incircuit q is arbitrarily set at 20% below crystal q or 80,000. then r load = (2 p f o l s /q) r s where l s and r s are crystal parameters. step 5: simultaneously solve, using a computer, (with feedback phase shift = 180 ) x c ? x c2 b = r ? r e + x c2 (x e x c ) (1) = x c load (where the loading capacitor is an external load, not including co) r e xc 2 (2) x e = x c2 + x c + r (3) rx c o x c2 [(x c + x c2 ) (x c + x c o ) x c (x c + x c o + x c2 )] r load = x 2 c2 (x c + x c o ) 2 + r 2 (x c + x c o + x c2 ) 2 here r = r out + r1. r out is amp output resistance, r1 is z. the c corresponding to x c is given by c = c1 + c in . alternately, pick a value for r1 (i.e., let r1 = r s ). solve equations 1 and 2 for c1 and c2. use equation 3 and the fact that q = 2 p f o l s /(r s + r load ) to find incircuit q. if q is not satisfactory pick another value for r1 and repeat the procedure. choosing r1 power is dissipated in the ef fective series resistance of the crystal. the drive level specified by the crystal manufacturer is the maximum stress that a crystal can withstand without damage or excessive shift in frequency r1 limits the drive level. to verify that the maximum dc supply voltage does not overdrive the crystal, monitor the output frequency as a func - tion of voltage at osc out 2 (pin 9). the frequency should increase very slightly as the dc supply voltage is increased. an overdriven crystal will decrease in frequency or become unstable with an increase in supply voltage. the operating supply voltage must be reduced or r1 must be increased in value it the overdriven condition exists. the user should note that the oscillator startup time is proportional to the value of r1. selecting r f the feedback resistor, r f , typically ranges up to 20 m w . r f determines the gain and bandwidth of the amplifier . proper bandwidth insures oscillation at the correct frequency plus rolloff to minimize gain at undesirable frequencies, such as the first overtone. r f must be large enough so as to not af fect the phase of the feedback network in an appreciable manner . acknowledgements and recommended references the following publications were used in preparing this data sheet and are hereby acknowledged and recommended for reading: technical note tn24, statek corp. technical note tn7, statek corp. d. babin, adesigning crystal oscillatorso, machine design, march 7, 1985. d. b abin , a guideline s f o r c rysta l o scillato r d esigno, machine design, april 25, 1985. also recommended for reading: e. hafner , athe piezoelectric crystal unit definitions and method of measuremento, proc. ieee, v ol. 57, no. 2, feb. 1969. d. k emper , l . r osine , a quart z c rystal s f o r f requency controlo, electrotechnology, june, 1969. p. j. ottowitz, aa guide to crystal selectiono, electronic design, may, 1966.
